Persons under the influence
These should be avoided, but sometimes it can’t be helped. First of all, you will need to decide whether they are fit for a normal seat or need a stretcher. You will need at least two escorts for both restraint and emergency evacuation, and a suitable receptacle for vomit.
As with prisoners, land as soon as practicable if there are any signs of violence. Further movement should be undertaken by surface means.

Bodies and remains
Their carriage is affected by how inaccessible they are, that is, precluding other methods of transport. The main considerations are the health and hygiene of the aircraft occupants, which means they might have to be carried outside if they are a bit ripe, so you need to be current on winching or slung loads. Whatever you choose, bodies and remains should be in body bags or coffins. Naturally, any spillage of body fluids needs a thorough wash down as soon as possible.

Police Dogs
Should be embarked or disembarked with the aircraft shut down, but if this is not possible, the observer should meet the handler and dog clear of the aircraft for the briefing. The dog should be on a short lead, so it doesn’t interfere with anything.
Fly smoothly, but be prepared to land if the dog becomes unwell, although you will find that they mostly like travelling and prefer to look out of the window rather than being made to lie down. If the dog breaks free and goes for the tail rotor or propeller(s), the handler must not attempt to follow, but give you a signal to close down.

Weapons and Munitions
The overriding consideration is the elimination of danger to the aircraft, its occupants and persons and property on the ground. Munitions include gas/smoke canisters, stun grenades, shotgun cartridges and ammunition for rifles and sidearms.
These should not be carried in a loaded state:
.
double-barrelled shotgun

.  
single-barrelled shotgun (unless automatic or pump action)

.
baton gun

.
CS discharger

.
dartgun

Loading, unloading or firing of weapons on aircraft is not permitted.
Where all passengers are securely seated throughout the flight, loaded weapons must be in a safe condition, weapons and munitions should be carried in holds, compartments, or other areas that are inaccessible in flight, and secured normally.
Weapons or munitions must not be distributed among passengers until the aircraft has landed.
Weapon Safe Condition

Working parts forward and trigger released, safety catch applied where possible, magazine charged with ammunition and fitted to the weapon. NO ROUND IN THE BREACH.
